<p>Extract information from a subversion working copy</p>
<p>The module defines the following variables:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>Subversion_SVN_EXECUTABLE - path to svn command line client
Subversion_VERSION_SVN - version of svn command line client
Subversion_FOUND - true if the command line client was found
SUBVERSION_FOUND - same as Subversion_FOUND, set for compatibility reasons
</pre></div>
</div>
<p>The minimum required version of Subversion can be specified using the
standard syntax, e.g. <code class="docutils literal notranslate"><span class="pre">find_package(Subversion</span> <span class="pre">1.4)</span></code>.</p>
<p>If the command line client executable is found two macros are defined:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>Subversion_WC_INFO(&lt;dir&gt; &lt;var-prefix&gt; [IGNORE_SVN_FAILURE])
Subversion_WC_LOG(&lt;dir&gt; &lt;var-prefix&gt;)
</pre></div>
</div>
<p><code class="docutils literal notranslate"><span class="pre">Subversion_WC_INFO</span></code> extracts information of a subversion working copy at a
given location.  This macro defines the following variables if running
Subversion’s <code class="docutils literal notranslate"><span class="pre">info</span></code> command on <code class="docutils literal notranslate"><span class="pre">&lt;dir&gt;</span></code> succeeds; otherwise a
<code class="docutils literal notranslate"><span class="pre">SEND_ERROR</span></code> message is generated. The error can be ignored by providing the
<code class="docutils literal notranslate"><span class="pre">IGNORE_SVN_FAILURE</span></code> option, which causes these variables to remain
undefined.</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>&lt;var-prefix&gt;_WC_URL - url of the repository (at &lt;dir&gt;)
&lt;var-prefix&gt;_WC_ROOT - root url of the repository
&lt;var-prefix&gt;_WC_REVISION - current revision
&lt;var-prefix&gt;_WC_LAST_CHANGED_AUTHOR - author of last commit
&lt;var-prefix&gt;_WC_LAST_CHANGED_DATE - date of last commit
&lt;var-prefix&gt;_WC_LAST_CHANGED_REV - revision of last commit
&lt;var-prefix&gt;_WC_INFO - output of command `svn info &lt;dir&gt;&#39;
</pre></div>
</div>
<p><code class="docutils literal notranslate"><span class="pre">Subversion_WC_LOG</span></code> retrieves the log message of the base revision of a
subversion working copy at a given location.  This macro defines the variable:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>&lt;var-prefix&gt;_LAST_CHANGED_LOG - last log of base revision
</pre></div>
</div>
<p>Example usage:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>find_package(Subversion)
if(SUBVERSION_FOUND)
  Subversion_WC_INFO(${PROJECT_SOURCE_DIR} Project)
  message(&quot;Current revision is ${Project_WC_REVISION}&quot;)
  Subversion_WC_LOG(${PROJECT_SOURCE_DIR} Project)
  message(&quot;Last changed log is ${Project_LAST_CHANGED_LOG}&quot;)
endif()
